haha yea i know what u mean nodsu, but what i was getting at, is when windows installs it chooses its basic driver which works with 99.999999999% of the worlds monitors, but then these systems we use, have i dunno somthing weird in them which makes windows want to change monitor drivers when the units are taken off our test screens (used for building them) and taken out to site and connected to another brand of monitor. they then go black just after the windows loading logo.
